31
The ______ are paired masses of gray matter in each cerebral hemisphere that coordinate movement
Basal nuclei
32
The limbic system include
Hippocampus and amygdala
33
memory and learning
Hippocampus
34
plays a role in behavioral expression and emotion
Amygdala
35
controls information entry into the cerebral cortex; edits, sorts and routes stimuli
Thalamus
36
regulates autonomic nervous system • Sleep/wake cycle • Thirst/hunger • Body temperature • Hormone production • Controls secretion from the pituitary gland
Hypothalamus
37
processes and routes visual and auditory stimuli to the thalamus, motor fibers from cerebral cortex, monitors movement from basal nuclei
Midbrain
38
breathing, reflexes, sleep/wake cycle
Pons
39
white matter for movement and sensation, regulates homeostatic functions
Medulla oblangata
40
sleep and arousal, pain transmission, mood regulation, involved in many homeostatic functions
Reticular formation
41
Function of recollective memory
Mammillary body
42
Secretaries melatonin
Pineal gland
43
monitors and coordinates movement
Cerebellum
44
Internal white matter looks like a tree in cerebellum
Arbor vitae
45
of ventricles are small capillaries in each of the 4 ventricles that produce the CSF
Choroid plexus
46
receive information about smells from the nose and send it to the brain by way of the olfactory tracts.
Olfactory bulb
47
connects the olfactory bulb to the remainder of the cerebral cortex.
Olfactory tract
48
carry visual information from the optic chiasm to the left and right lateral geniculate bodies as a part of the visual pathway
Optic tract
49
channels that connect the paired lateral ventricles with the third ventricle at the midline of the brain.
Interverticular foremen
50
a fluid-filled canal that runs through the midbrain connecting the third and fourth ventricles.
Cerebral aqueduct
51
take signals from PNS to CNS
Afferent neurons – sensory
52
take signals from CNS to effectors
Efferent neurons – motor
53
carries information away from the cell body
Axon
54
carries information to the cell body
Dendrites
55
ribosomes and rough ER in the cell body
Nissl bodies
56
insulation around axon and makes conduction faster
Myelin sheath
57
cell membrane surrounding axon
Axolemma
58
cytoplasm within the axon
Axoplasm
59
where axon originates from cell body
Axon hillock
60
branches from central axon
Collaterals
61
fine branches at the end of axons
Telodendria
62
(synaptic knobs): innervates target cells
Axon terminals
63
spaces between myelin sheath allowing conduction
Node of raniver
64
one axon with two or more dendrites and usually a branched dendritic tree • Motor (efferent), interneurons • Location: most neurons in CNS and motor neurons in PNS
Multipolar neurons
65
one axon and one dendrite • Sensory (afferent) • Location: special sense organs in PNS (retina)

71
presynaptic and postsynaptic membrane separated by synaptic cleft • diffusion of neurotransmitters across the synaptic cleft causes an action potential in the postsynaptic membrane
Chemical synapse
72
joined by gap junctions allowing electrical currents to flow through cells
Electrical synapse
